Second Revision No. 14 simplifies the electrical area classification provisions for button tippers and test baths by combining them into a single subsection. This is appropriate, since the requirements are identical. In addition, the provisions are limited in applicability to those products that contain flammable gases or flammable liquids, because electrical area classification is unnecessary where the components of the product do not present a risk of ignition. Additional guidance is given in the Annex to 5.5.3. See Second Revision No. 15.

Second Revision No. 8-NFPA 30B-2013 [ New Section after A.1.7 ]
A.1.8.1(3) Fire testing with alcohol and water at this percentage in plastic bottles has been successful. Small-scale burn tests of aerosol products in plastic containers have shown the aerosol with a nonflammable propellant to behave the same as the aerosol with no propellant. A.1.8.1(4) A fire test with a formula of this type using liquefied petroleum gas was successful. An emulsion in an aerosol product is a mixture of two or more liquids, one of which is present as droplets of microscopic or ultramicroscopic size distributed throughout the other. Emulsions are formed from the component liquids either spontaneously or, more often, by mechanical means such as agitation, provided that the liquids that are mixed have no (or a very limited) mutual solubility. Emulsions are stabilized by agents that form films at the surface of the droplets (e.g., soap molecules) or that impart to them a mechanical stability (e.g., colloidal carbon or bentonite). Colloidal distributions or suspension of one or more liquid(s) with another liquid will have a shelf life that varies with the efficiency of the recipe used.

The principal concern in the event of a shrink-wrap tunnel failure is the risk of aerosol container failure and subsequent fire. In the event of a container failure, significant ejection speeds, sympathetic failures of adjacent containers, and hot surfaces present serious potential exposures. In turn, ignition of flammable solvent or propellant vapor can result, . T with t he consequence of this is that an explosion can further augment the original ejection force. This can be a significant hazard to operators in the vicinity. Newly installed shrink-wrapping machines should be equipped with numerous safety features and . E e quipment suppliers should be advised of these such features prior to placing orders. The high fire risk associated with shrink-wrap tunnels should be considered when determining their location. Shrink-wrap acts as a very good insulator, which can facilitate overheating during its passage through the tunnel. Some containers can act as very efficient heat sinks, resulting in fast heating of the containers if the film fails. This can also be exacerbated by the use of high proportions of substances with low specific heats in the formulations. Automatic film failure detection, which switches off the heater and stops the machine in-feed, is necessary. The following list is offers further guidance: (1) The shrink-wrap machine design should ensure that containers are prevented from being trapped in the heating tunnel by internal obstructions. (2) An alarm should be activated in the event of unplanned stoppage. (3) The shrink-wrap machine should have a secondary means of keeping the tunnel conveyer moving in the event of power failure. (4) In the event of conveyor power failure, standby power is recommended in place of a back- up air motor. This cuts in to energize the conveyor if any phase drops more than 10 percent. The in-feed gate and heaters should also automatically switch off and the operator should be alerted by a suitable alarm. If an air motor system is installed, a dedicated air receiver should be connected via metal pipework. This receiver should store enough air to evacuate any “packs” in the tunnel and be constantly fed by the compressor via a non- return valve. An air pressure switch should be installed to interlock with the shrink-wrapper control system. Neither of these back-up systems backup system will be of any use if the belt itself or transmission is broken, so a motion detector should also be installed to confirm belt movement and initiate the above shutdown described if the belt stops during production. (5) Operator protection training should include the use of appropriate personal protective equipment (PPE) in the event containers or collations must be removed manually during a breakdown or unplanned stoppage. (6) Automatically operated fire suppression systems should be installed in accordance with applicable NFPA codes and standards. Portable fire extinguishers should be provided and located in accordance with NFPA 10. , Standard for Portable Fire Extinguishers . (7) There should be a half-hour 30–minute fire-resistant partition or other equivalent means to prevent the spread of fire between the shrink-wrapping machine and the remainder of the aerosol product filling line. (8) Access to and escape routes from the shrink-wrapping machine should be kept clear at all times. (9) Supplies of packaging materials should be stored or staged in defined areas away from the shrinkwrapping machine. (10) There should be an automatic device to detect film failure and prevent new collations from being allowed to enter the heating tunnel in the event of a film failure. (11) A pusher rod with a flat plate on the end, that is specifically designed for the shape of the heating tunnel or equivalent system, should be provided. This The rod will allow operators to rapidly clear the heating tunnel of all collations and containers in the event of a total conveyer failure. (12) A suitable means of ensuring that trapped aerosol containers can be rapidly removed from the tunnel (because either the conveyor has stopped or they have caught on some obstruction) is essential. The inside of the tunnel should be designed with sloping sides to prevent loose aerosol products containers from being retained under the heaters. The design of such a system needs to provide for the protection of operators removing aerosol products containers trapped in the heating tunnel, as because a fully pressurized aerosol container that fails — as well as and its contents — can be ejected with considerable force. Therefore, a remote-operated or automatic mechanism or system could might be preferable. The above procedure described should only be carried out only if aerosol products containers have remained in the tunnel for a short time and the operator is aware

that it is within a safe period. (13) The operator should be provided with the necessary PPE and be trained in its proper use, the proper use of the pusher rod, and the risks involved. (14) A switch should be installed to allow the power supply to the tunnel heat to be turned off in the event of an emergency. (15) The tunnel heater power switch should be provided with automatic shutdown systems that are manually reset. (16) An emergency air blower or other means of rapidly cooling the tunnel should be installed according to the specification provided by the equipment supplier, unless an automatic fire suppression system is provided. (17) Detectors should be installed to count collations in and out of the heating tunnel to activate heater power cutouts and alarms and to stop in-feed gates in the event of a tunnel blockage. (18) Heated surfaces can ignite burst containers, so attention container stability must be provided to ensure container stability ensured , especially when wrapping containers are being unwrapped without trays. If there is a likelihood of unstable containers in this area, appropriate sensors should be installed to inhibit the in-feed gate until the containers are removed. Installing gaseous or dry chemical automatic protection into the shrink-wrapper tunnel is an effective way to directly reach the source of fire. Such systems can be activated by the operator from a safe location, or installed to automatically activate by optical flame detectors located at each end of the tunnel. In addition to the tunnel, the discharge nozzles should also cover the film sealing area. (19) The fire suppression system should be connected to the building fire alarm system. (20) Where conveyers feed shrink-wrapped collations to further automatic equipment downstream from the shrink-wrapping machine, there should be an out-feed light curtain or similar device to detect back- up from the downstream equipment and to stop the in-feed gate until there is no longer a backup. (21) There should be a device installed to detect excess temperatures in the heating tunnel, producing an alarm, cutting power to the heaters, starting the air blowers (if installed), and stopping the in-feed gate. (22) The excess temperature detector should be calibrated at regular specified intervals and the results recorded. (23) A tunnel temperature indicator should be installed for operator information and maintenance purposes showing low, normal, and high/excess bands. (24) The temperature indicator should be calibrated at regular specified intervals and the results recorded. (25) All electrical resets on shrink-wrappers should be manually operated only. (26) Safeguarding should be provided to prevent injury to operators from ejecting ejected containers and contact with hot surfaces.

The automatic fire protection alternatives given in Chapter 6 of this code are derived from more than a dozen aerosol product fire tests conducted by a major insurance company in the late 1970s and early 1980s [see Table B.1(a) and Table B.1(b) ], and more than 50 small-, medium-, and large-scale tests sponsored by the aerosol products industry in the 1980s [see Table B.1(c) through Table B.1(g) ]. This aerosol products fire research represents a significant body of knowledge regarding aerosol fire development and control for various types of aerosol products in metal containers in various storage and protection scenarios. A complete and detailed history of these aerosol product storage research efforts can be obtained on request from the Chemical Specialities Manufacturers Association, Inc., in the form of a series of articles entitled “An Industry Responds: A Technical History of the CSMA Aerosol Warehouse Storage Fire Protection Research Program.” Send requests to the attention of the Director of Scientific Affairs, Chemical Specialities Manufacturers Association, Inc., 1913 I Street N.W., Washington, DC 20006. Aerosol product warehouse storage fires, using standard fire test igniters, begin as cardboard fires. The fire grows up the flue, burning off the aerosol carton faces, and there is usually a flame 1.5 m to 3.0 m (5 ft to 10 ft) above the top of the array before the first aerosol container ruptures and aerosol products become involved in the fire. Depending on the type of aerosol product, the first container rupture tends to occur at 30 seconds to 60 seconds after ignition in rack storage arrays and 90 seconds to 120 seconds in palletized storage arrays. When aerosol containers begin to rupture, some of the heat from the fuel added by the aerosol product goes quickly to the ceiling, while some is absorbed into other aerosol products, bringing them closer to, or exceeding, their burst pressure. Early application of adequate densities of sprinkler water is the most effective way to control or suppress an aerosol product fire, avoiding a chain reaction that can lead to loss of control. For this reason, early suppression fast response ( ESFR) sprinkler protection is especially effective for aerosol products. Table B.1(a) Spray Sprinkler Tests Test No. 1

Beginning with the first edition of NFPA 30B in 1990, aerosol products in plastic aerosol containers have been limited to a maximum size of 118 ml (4 fl oz) while metal aerosol containers have had a maximum size of 1000 ml (33.8 fl oz). This is based on both the U.S. Department of Transportation (DOT) limitations and the absence of fire research involving aerosol products in plastic containers. The DOT has recently removed the smaller size restriction on aerosol products in plastic aerosol containers. Plastic containers for combustible and flammable liquids have been found to be a greater fire risk than metal containers. The assumption is then that plastic might pose a greater risk than metal when used as containers for aerosol products. The recent removal of the DOT limitation has prompted the beginning of fire research with aerosol products in plastic containers. , and initial Initial tests are now recorded presented in this Annex C. Table C.1(a) is taken from Table 1 of the Underwriters Laboratories Inc. (UL) Research Technical Report, “Palletized Plastic Aerosol Storage Testing Result.” This table summarizes a full-scale test conducted by Underwriters Laboratories UL and sponsored by a manufacturer of aerosol products. This test of aerosols aerosol products in plastic containers on wood pallets was conducted with control mode specific application (CMSA) sprinkler protection.
